Q. Can flat feet be repaired by surgery? I have flat feet and I’m looking for all sorts of treatments for it- I heard there is a surgery for it- is it helpful?
A. As far as I know- they don’t treat flat feet that are asymptomatic. So first of all check if it bothers you. secondly there are 2 kinds of flat feet- rigid and flexible. There are different and treated differently. Not always a surgery (which is very painful and costly) is needed– I went to a Rolf method therapist by the advice of my orthopedic and it’s much better now. Ask an orthopedic.
